Description

I am running clickhouse using docker in lime and I found that after upgrading to lima 0.8.2, CPU SSSE3 is no supported, is this expected?

PR #494 use qemu64 CPU instead of Haswell-v4, qemu64 CPU does not contain the instruction set of SSSE3 by default.

PR #494 use qemu64 CPU instead of Haswell-v4, qemu64 CPU does not contain the instruction set of SSSE3 by default.

I'm not sure why that switch was made; I assumed that qemu64 provided better performance. If so, then the question may be if having SSSE3 support will make up for not getting the other gains from switching to qemu64.

I guess it would be nice to know the actual benchmarks used for comparison, and what the numbers are.

Either way, implementing #592 to give the user an option seems like a good idea.

SGTM.
